Gabriel G63605 Ultra Truck Front Shock Absorbers - Smooth Ride

In this review the Gabriel G63605 Ultra Truck front shock absorber is evaluated for truck and motorhome owners who need a durable OE replacement. The bottom line: it is best suited to older Dodge motorhome chassis, certain John Deere and Oshkosh front applications, and owners who want firmer, controlled handling. The review finds the G63605 delivers noticeable ride control thanks to Gabriel's G-Force technology and a precision twin-tube design, while remaining a straightforward bolt-on fit for compatible front mounting points.

Key Features

• Vehicle Fitment: Designed to fit a range of Dodge M300/M350 and motorhome chassis applications, ensuring correct front-end compatibility for specified models.
• Premium Damping Technology: G-Force infinitely variable damping provides more responsive control across mixed road conditions for improved handling.
• Durable Construction: Twin-tube engineering and a super finished chromed piston help resist wear and extend service life under normal driving conditions.
• Ease of Installation: Simple bolt-on design matches the specified upper and lower mount codes for a straightforward replacement process.
• Specific Dimensions: Known stroke, extended, and collapsed lengths allow buyers to confirm fit before purchase, reducing installation surprises.

Who It's For

The Gabriel G63605 is aimed at owners of compatible older Dodge trucks and motorhomes who need a front shock that restores firmer control and a more planted feel. It also suits service fleets or restorers working with chassis that list the listed interchange numbers and mount codes.

Buyers who prefer a very soft, cushioned ride or who lack the exact listed fitment (upper mount EB19, lower mount ES27) should look elsewhere. Modern light trucks and SUVs with different mounting or length requirements will need a model matched to their specific chassis.

Pros & Cons

Pros

• Solid ride control from Gabriel's G-Force technology improves handling compared with worn OE units.
• Good value and relatively easy to install as a bolt-on OE replacement for listed vehicles.
• Durable components and precision finishes help resist wear during normal use.

Cons

• Some users report a firmer-than-original stiffness, which may not suit those wanting a softer ride.
• Fitment is specific to certain Dodge, John Deere, and Oshkosh motorhome applications, so verification is required before purchase.
